738 grams water (1 mole H2O/18.016 grams)(2 mole H/1 mole H2O)(6.022 X 10^23/1 mole H)
= 4.93 X 10^25 atoms of hydrogen
A water molecule (H2O) contain two hydrogen atoms.
5.839 grams C8H8 ( 1 mole C8H8/104.144 grams)(8 mole H/1 mole C8H8)(6.022 X 1023/1 mole H) = 2.701 X 1023 atoms of hydrogen --------------------------------------------
hydrogen is H2, with a molecuar weight of 2.016. In 1.008 grams of H2 there are 3.011 X 10 raised to power 23 (approx) 2.011 X 1023 molecules or 6.022 X 1023 atoms. Ovviously you can go straight to the answer as the weight is the atomic mass in grams.
The % of hydrogen is superfluous information 1.5 lb H2O2 (454 grams/1 lb)(1 mole H2O2/34.016 grams)(2 mole H/1 mole H2O2)(6.022 X 10^23/1 mole H) = 2.4 X 10^25 atoms of hydrogen
None. Hydrogen is an element. It contains only hydrogen atoms.
6.6x1022 per gram of water
45,0 grams of hydrogen gas have 135,5.10e23 atoms.
1,204428358.1023 atoms of hydrogen
1,25 grams of CH4 contain 0,156696.10e23 atoms.
3.05 x 1025
2 hydrogen atoms per molecule of water.
there are 2 atoms of hydrogen in water
1 third because water is composed by 2 oxygen atoms and 1 of hidrogen, so 207÷3=69 grams.
Quite a few! 871 grams water (1 mole H2O/18.016 grams)(2 moles H/1 mole H2O)(6.022 X 1023/1 mole H) = 5.82 X 1025 atoms of hydrogen ========================
3.65 grams of water is equal to .203 moles of H2O. This means there is also .203 moles of H2 present, or .408 grams.
H2OCount two atoms hydrogen in one molecule of water.
There are 4 atoms of hydrogen in 2H2O.
